CROSS-REFERENCE TO A RELATED APPLICATION

This application claims priority to European Community Plant VarietyOffice (CPVO) Plant Breeder's Rights Application No. 2020/2633 filed onOct. 27, 2020, under 35 U.S.C. 119(f), the entire contents of which isincorporated by reference herein.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Curioplant, botanically known as Curio ficoides ‘Blues’ and will be referredto hereinafter by its cultivar name, ‘Blues’. The new cultivar of Curiois an herbaceous perennial grown for container and landscape use.

The new cultivar was derived from a controlled breeding programconducted by the Westerbork, The Netherlands. The overall purpose of thebreeding program was to develop new cultivars of Curio plants withupright, compact, and well-branched growth habits combined with longleaves that are fine in texture and blue in color.

‘Blues’ arose from a cross made in September of 2015 by the Inventorbetween Curio ficoides ‘Mount Everest’ (not patented) as the femaleparent and an unpatented selection from the Inventor's breeding program,designated as accession number S1501K1 as the male parent. ‘Blues’ wasselected as a single unique plant by the Inventor in 2016 in Westerbork,The Netherlands.

Asexual propagation of the new cultivar was first accomplished bycuttings in 2017 by the Inventor in Paterswolde, The Netherlands.Propagation by cuttings has shown that the unique features of the newcultivar are stable and reproduced true to type in successivegenerations.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and are determined tobe the characteristics of the new cultivar. These attributes incombination distinguish ‘Blues’ as a unique cultivar of Curio.

1. ‘Blues’ exhibits a very well-branched and compact plant habit.2. ‘Blues’ exhibits an upright growth habit.3. ‘Blues’ exhibits blue foliage color.4. ‘Blues’ exhibits long leaves with a fine texture.

The female parent is similar to ‘Blues’ in having foliage that is bluein color and an upright growth habit. The female parent differs from‘Blues’ in having larger leaves that are wider and thicker, a lesscompact plant habit, and has less branches. The male parent is similarto ‘Blues’ in foliage color but differs from ‘Blues’ in having finerleaves and a more compact plant habit. ‘Blues’ can be most closelycompared to Curio ficoides ‘AMICU1909’ (not patented). ‘AMICU1909’ issimilar to ‘Blues’ in having overall blueish color foliage. ‘AMICU1909’differs from ‘Blues’ in having a shorter plant height, foliage that hasa blend of green and grey colors with the blue color, and thickerleaves.
